The invention provides a novel peroxide scavenger comprising a phosphine compound represented by general formula [I]:
wherein Z

each represents a cyclic group, particularly a peroxide scavenger that can scavenge peroxides such as reactive oxygen species which are generated in mitochondria upon exposure to oxidative stress and localized in mitochondria. The phosphine compound of the invention is oxidized by the peroxides localized in mitochondria to increase the fluorescence intensity, whereby the peroxides can be scavenged.
该发明提供了一种新型过氧化物清除剂,包括由通式[I]所表示的膦化合物:其中Z1和Z2分别表示环状基团;Ar表示芳基基团;R表示脂肪烃基团;Y表示磷(P)、氮(N)或铋(Bi);而R1、R2和R3分别表示环状基团,特别是一种过氧化物清除剂,可以清除在暴露于氧化应激时在线粒体中生成并定位在线粒体中的反应性氧化物种,该发明的膦化合物被定位在线粒体中的过氧化物氧化以增加荧光强度,从而可以清除过氧化物。
